An older component, specifically, RadEditor 5.6.5.0 is not rendering to Firefox 11.0. It sees it as an unsupported browser and simply renders a textarea tag instead. Is there a way to have the control treat it as a lower version of Firefox?
The answer is to update the ClientTarget
Page.ClientTarget = "Uplevel";
